ENVELOP.

SPECIFICATION forming part of Letters Patent N o. 768,670, dated August 30, 1904. Application led January 20, 1903. Serial No. 139,792. (No model.)

To ft2/Z wwnt it 711/601/ concern.'

Be it known that I, JOHN THOMAS MARTIN, a citizen of the United States, residing at Muscatine, in the county of Muscatine and State of Iowa, have invented a new and useful Envelop, of which the following is a specification.

My invention relates to envelops, more particularly to envelops designed for use in keeping card-records, such as records of attendance in Sunday-schools and the like.

The object of my invention is to provide an envelop having a main pocket in which all of the cards representing the various members of a class are to be kept and having' a supplemental pocket into which the teacher of the class may put the cards representing absentees at each meeting of the class.

The construction of my improved envelop will appeal' in the following description and accompanying drawings, and the novel features thereof will be particularly pointed out in the appended claims.

Referring to the drawings, Figure l shows the preferred form of blank used in making my improved envelop. Fig. 2shows the first step in the manufacture of the envelop from the blank. Fig. 3 shows a completed envelop. Fig. 4 shows a slightly-modified form of the free end of the end flap 3. Fig. 5 is a back view of the lower portion of a completed envelop, showing a modified mode of attachment of the marginal fiaps 4 4 to the body of the envelop.

In the various views corresponding parts are indicated by the same characters of reference throughout.

The blank from which my improved envelop is constructed consists, essentially, of a body portion l, side fiaps 2 2, and an end flap 3, which serves to form the outer wall of the supplemental pocket. The end flap 3 is preferably provided with narrow marginal flaps 4 4` which are adapted to be folded over upon the end iap 3 when the side iiaps 2 2 are folded over upon the body portion ofthe blank. The end flap 3 is also preferably provided with another narrow marginal flap 5 at the free end thereof, which is to be folded over and pasted down upon the end iap 3 in order to form a reinforcement to strengthen the free margin of the supplemental pocket. At the top of the body portion 1 a flap-closure 6 is preferably provided to furnish additional protection for the record-cards when stored away in the main pocket of the envelop.

The mode of constructing the envelop from the blank will be readily understood from the drawings. The first step, as shown in Fig. 2, consists in folding over upon the body portion the side iiaps 2 2, which are to be secured by pasting. At the same time that the side fiaps are folded over upon the body portion the narrow marginal flaps 4 4 are folded over upon the end iap 3. The next step after the folding' and pasting together of the side flaps 2 2 is to fold over the narrow marginal flap 5 upon the end flap 3 and paste it securely thereto to form a reinforcement, as above eX- plained. The fiap 5 having been pasted down securely on the end iiap 3, the end Hap is folded upward against the previously folded and pasted side flaps 2 2 and fastened in position by pasting the marginal flaps 4 4 to the side aps 2 2, which operation completes the manufacture of the envelop. When the iiap 3 is made with the end formed in the manner shown in Fig. 4, the foldable margin 5 forms a reinforce for the free upper edge of the supplemental pocket, which extends entirely across the pocket and is connected with a main pocket by having the ends pasted either to the flaps 2 2 or to the body portion l of the blank. l/Vhen the reinforce is formed in this manner, the free margin of the supplemental pocket is so strengthened that tearing of the material of the pocket when introducing cards into the pocket is almost impossible.

The modified structure shown in Fig. 5 is designed to give additional strength to the connection between the supplemental pocket and the main pocket when the envelops are to be subjected to very hard usage; but the form of the invention shown in Figs. l, 2, and 3 is adapted to meet all ordinary requirements,`

and the envelop so constructed presents a somewhat more pleasing appearance' than either of the modified forms.

The improved'envelop is designed especially for use in keeping records of attendance in Sunday-school classes by means of roo the card system; but it may be used in keeping accounts or in tabulating memoranda or for other similar purposes, lVhen used in keeping' records of attendance in Sundayschools, the mode of employment is as follows: Each member' of the class is represented by a card bearing his name and preferably provid ed with spaces representing each Sunday in the year. These cards are all permanently stored in the main pocket of the envelop, and the envelops for the various classes in the Sundayschool are to be kept in a suitable receptacle by the secretary. The envelops are distributed to the various classes every Sunday and the cards taken from the envelops. Then those representing absent pupils are placed in the supplemental pocket, the others being' returned to the main pocket. The envelops are then collected by the secretary, and the cards representing the absentees and contained in the supplemental pockets may be punched and any desired memoranda made therefrom before they are returned to the main pockets of the envelops with the other cards. By the use of envelops of this kind it will be readily seen that the card-records of attendance in Sundayschools may be kept with very little effort and inconvenience on the part either of the teachers or the secretary. It will also be readily seen that by having` the cards of the absentees separated from those present, and yet keeping' all of the cards of each class in a single envelop, it will be much easier for the secretary to prepare his g'eneral report of total attendance than if the cards were not so kept.

l/Vhat l claim as new, and desire to secure l by Letters Patent, isM

l. An envelop having' a main and a supplemental pocket and formed from a single blank, the blank comprising a body portion, side flaps, and an end liap having foldable marginal portions at its sides and end, the main pocket being formed by folding over and pasting together the side flaps, and the supplemental pocket being formed by folding the end flap over and upon the folded side fiaps, pasting the side margins of said end iiap upon some suitable portion of the main pocket and folding the marginal portion at the end of said end iiap and securing' the ends of said folded-over marginal portion of the end flap to the body portion of the blank.

2. An envelop having a main and a supplemental pocket, formed from a single blank comprising' a body portion, side flaps, andan end flap, said end iap beingprovided with foldable marginal portions at its sides and end, and the marginal portions being divided near the free ends thereof by transverse cuts, the main pocket being formed by folding over and pasting' the side flaps, and the supplemental pocket being formed by folding the end Hap upon the side fiaps, pasting the foldable side margins of said end flap to suitable portions of the main pocket, folding the end margin of said end iiap to form a reinforce and pasting' the ends of said reinforced portion upon the body portion of the envelop.

YIn testimony that I claim the foregoing' as my own I have hereto affixed my signature in the presence of two witnesses.
